MACHINE FOR BARB ING METALLIC STRIPS.

SPECIFICATION forming part of Letters Patent No. 323,713, dated August 4, 1885.

Application filed November 5, 1884. No model.)

." all whom, it may concern Be it known that I, THOMAS HENRY MOR- GAN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in a Machine for Barbing Metallic Strips, of which the following is a specification, reference being had to the accompanying drawings.

My invent-ion is a machine for barbing metallic strips.

It consists in two contiguous rolls provided on their peripheries with adjustable and removable punches set in openings,and recesses I 5 having adjustable and iemovable dies therein, the punch in one roll meshing with the diein the contiguous roll when the rolls are rotated. It also consistsin other details of construction, all of which will be more fully hereinafter 2o specified, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of the machine. Fig.

2 is a front elevation. Fig. 3 is a detail of the rolls,showing a punch in the'lower roll in the recessed die of the upper roll, a portion of the flange at the side of the lower die being broken away. In this view the upper roll is in section to show the set-screws whereby the punches and dies are adjusted. Fig. 4 repre- 0 sents two forms in perspective of the punches, and Fig. 5 is a perspective view of the sunken or recessed die.

Most machines for barbing purposes with which I am familiar are provided with feed- 5 rolls and Vertical punches. By placing the punches and dies in the face of the harbingrolls and having themmesh, as herein shown, I am enabled to dispense with said fced-rolls. My rolls, dies, and punches perform the douhis function of feeding, cutting, and bending, the stock being drawn between the contiguous rolls and barbed simultaneously.

Like letters indicate corresponding parts throughout the several views.

A A represent the two sides of the frame or housing, between which is mounted the meshing gear-wheels B B.

0 represents the upper shaft, journaled in the housing-boxes G 0. One end of said shaft extends outside of the housing, and it is provided with the upper barbing-roll, D.

E is the pulley-shaft, mounted in the housing-boxes E. One end of this shaft is pro vided with the pulley F. To the other end of said shaft the lower barbing-roll, G, is se- 5 cured. The two rolls D G are keyed or otherwise rigidly secured to their respective shafts. Thelower roll, G, is provided with side flanges,

G. The space between the flanges is about equal to the width of the face of the upper roll, D. The face of said upper roll is practically contiguous to the face of the lower roll, the flanges serving to prevent any lateral variation in the relative positions of the rolls.

H H are set-screws to hold the j ournal-boxes in position and regulate the bite of the rolls on the stock to be barbed. There are four of these set-screws in the machine herein shown, one above each box. There are threaded vertical openings in the housing for the reception of said screws.

I represents a series of openings at regular intervals in the rolls. These openings are through the sides.

J indicates openings in the face ofthe rolls, in which the dies and meshing punches are alternately placed. There is a threaded open ing between the openings I and J, in which is placed the set-screw L. The point of this screw rests against the inner end of the die or punch.

M represents the recessed die. This die is inserted into the opening J in the face of one of the rolls with one end thereof, M, resting against the point of the set-screw L.

N represents the punch, one end of which, N, rests against the point of the set-screw L in the opening J in the face of the rolls. The protruding end of said punch N meshes into the recessed portion M of the die when the 0 rolls are rotated.

O 0 represent central circumferential grooves in the respective faces of the rolls for the reception of the rib, which is usually on the strips of the stock to be barbed. P Pare guide-plates secured to the housing. These plates are provided with openings P, through which the stock is fed to the rolls. Said openings are on a horizontal line with the contactpoint of the rolls. By putting these guideplates on each side of the machine the stock may be fed from either side, according to the movement of the rolls.

Q represents a setscrew passing through a threaded opening in the side of the rolls,which communicate with the opening J. (The open ing'for the set'screw Q is not shown.) The point of this set-screw engages the side of the die or punch and holds the same in place. The set-screw Q is only shown in Fig.

The operation of the machine is as follows: By rotating the pulley F the shaft E, gear B, and flanged roll G are rotated. The gear B meshes with the upper gear, B, and imparts motion thereto and to the shaft 0. The roll D, being rigidly fixed to said shaft, is also rotated. The gears are of equal diameters; so, also, are the rolls. Therefore when the punch and its receiving-die in the face of the opposite roll are adjusted to mesh the parts will accurately engage at each rotation. The stock is fed through the opening I in the guide-plate P, and is passed between the rolls.

The dies and punches may be set so as to barb only one side of the stock or both sides. Said dies and punches may also be adjusted so as to produce alternate barbs on the stripthat is to say, turn a barb up on one side and down 011 the other side, thus producing alternate barbs on both sides of the strip. The

punch slits the edge of the strip and forces the slit or barbed portion into the die.

The angle of inclination of the barbs from the strip may be regulated by the form of the punch and dies.

Having thus described my invention,I claim as new and desire to secure by Letters Patent- 1. The combination, with the barbingrolls having radial recesses I extending from their peripheries inward, of the removable and adjustable punches, and dies located in the opposite rolls, and the set-screws whereby said dies may be adjusted, substantially as specified.

2. The barbing-rolls provided with recesses I J, the recesses J having located therein the removable punches and dies, and the recesses I affording means for reaching the heads of the set-screws for the purpose of adjustment, substantially as specified.

3. The combination, with thebarbingrollers having the recesses I and J, of the punches and dies located in said recesses in the respective rolls and the set screws whereby they may be held in an adjusted position, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS HENRY MORGAN.
